Motioncasts is a paid series of screencasts and tutorials that walks you through some of the basic elements of RubyMotion and then progresses into more complicated pieces like Weak References and Autolayout.

A great post to read if you are new to RubyMotion and/or iOS development. Covers some very good basics to know as well as some not so obvious gotchas. At the moment this is a blog dedicated to RubyMotion, Steve has got some great content going I hope he keeps it up.

These are the resources I have found useful to me so far or have been told (the book) are. Please tweet your suggestions to me at @gertig or leave them in the comments.
